Two football players, Bubba and Tiny, were taking an important exam. If they failed, they would be on academic probation and not allowed to play in the big game the following week. The exam was "fill in the blank" and the last question read, "Old MacDonald had a_____." Bubba was stumped -- he had no idea what to answer, but he knew he needed to get this one right to be sure he passed.
Making sure the professor wasn't watching, he tapped Tiny in the shoulder. "Tiny, what's the answer to the last question?" Tiny laughed, then looked around to make sure the professor hadn't noticed. He turned to Bubba and said, "Bubba, you're so stupid. Everyone knows that Old MacDonald had a FARM."
"Oh yeah," said Bubba, "I remember now." he picked up his No. 2 pencil and started to write the answer in the blank. Then he stopped. Tapping Tiny on the shoulder, he whispered,
"Tiny, how do you spell farm?"
"You are really dumb, Bubba. That's so easy," hissed Tiny, "farm is spelled 'E-I-E-I-O'."
